This experiment was carried out to breed a very early maturing variety of Italian ryegrass (Lolium multiflorum Lam.) in Grassland and Forage Crops Division, National Institute of Animal Science, RDA, Cheonan from 2015 to 2017. New variety of Ryegrass, 'Green Call' is a diploid variety with green in leaf color and has semi-erect growth habit in late autumn and erect growth habit in early spring, 'Green Call' was on April 25 in heading date as a early-maturing variety. Also 'Green Call' was narrower by 2 mm in flag leaf width, longer by 1.3 cm in flag leaf length and shorter by 5 cm in plant height than those of control variety, 'Florida 80', respectively. 'Green Call' was also thicker by 0.14 mm in stem thickness and strong in winter hardness. Dry matter (DM) yield (11,592 kg/ha) of 'Green Call' was similar to that of 'Florida 80'. Total digestible nutrient (TDN), crude protein (CP) and relative feed value (RFV) of 'Green Call' were 60.8, 10.3 and 96.7 % which are 2.1, 1.1, 6.9 % higher than those of 'Florida 80', respectively. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) of 'Green Call' were 35.5 and 58.9 % which are 2.7 and 2.3 % lower than those of 'Florida 80', respectively.
